Trait Num 

pub trait Num
where
    Self: Default + Debug + Copy + PartialOrd<Self> + Add<Output = Self> + AddAssign + Sub<Output = Self> + SubAssign + Mul<Output = Self> + Div<Output = Self>,
{
    const INFINITY: Self;
    const NEG_INFINITY: Self;

    // Required methods
    fn from(i: i16) -> Self;
    fn abs(self) -> Self;
    fn powi(self, y: u32) -> Self;

    // Provided method
    fn rat(num: i16, denom: i16) -> Self { ... }
}

A trait that describes the operations necessary for this crate’s layout algorithms.

Required Associated Constants

const INFINITY: Self

const NEG_INFINITY: Self

Required Methods

fn from(i: i16) -> Self

fn abs(self) -> Self

fn powi(self, y: u32) -> Self

Provided Methods

fn rat(num: i16, denom: i16) -> Self

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.

Implementations on Foreign Types

impl Num for f32

Available on crate feature std only.
